This repository holds data collected for a series of experiments on the effects of exogenous cues on perceived contrast. While the data files are complete, the companion materials that describe the methods are being written, and should be uploaded shortly. In addition, post-processing scripts in the R programming language will be made available to facilitate checking the analyses; or even completely regenerating the article (submitted to PLoSONE). If you can't wait, please write to britt@uwaterloo.ca with questions.
